A further modification is shown in 6- 8.

. wherein the string l9 extendsunder the. outer layer 2|, just as in theform shown in Figs 1-3,7 but in Figs. 6-8 the free end'of string I9carriesa tape cutting or severing device 29 having two downturnedportions 30 and the upstanding serrated cutting edge portion 3|."

When the desired amount of tapehas been removed, the string,l9is again *placed underthe outer layer 2| ready for subsequent use. Thecutting device 29 may be made 'of sheet metal or any other suitablematerial.

In the modification shown in; Figs. 9-10' the adhesive tape I6 is,helically wound around the tubular member IS. A substantially ,U-shapedelement "straddles the outer face of the'roll of tape with its sideportions extending inwardly towards the center. of the member l5. Eachside portion H has an inturned projection 42 extending into the end 'oftubular member I 5 so that the two projections 42extend-towardseachpther and ber 15,. as clearly shown in Fig. 10.The-element 40 is preferably formed of sheet material and the Extendingoutwardly-from the part 43,'"which connects side portions 4| of element40, is aprodimensions of the parts are 'suchthat the element 40 ismounted forrelatively free'movement around the outer faceor periphery ofthe roll,

v I broughtinto position as shown in Fig. 9, the tape which has beenunrolled for use, may be severed v along cutting edge 45. f Since theinner face of the tape carries the adhesive or tacky'substancal it willbe evident that after piece of tape 46 has.

been cut off, the adjacent portion 41 of-the tape on the roll will beadhesively secured: to'the face a v 3 comprising a tubular member aboutwhich the tape' iswound, a plate secu'red-toone end oiisaid;

of projection 44. .When it is again desired to use a piece of "tape fromthe roll, the element 40 is moved away from the end "so that itsadhesive contact with prolection 44 is .broken 1 and the end 4'! ofthetape renderedavallable so I that it may be grasped by. the hand tounroll the desired amount of tape. The element 40 is again severed'onedge and the endof the'tape' ad- 1 hesively secured to projection 44ready for the .0 V i I o 5 I 4i! aifords not only a'cutting device forthe tape but also providesa ready and convenient means for adhesivelyholding theend of the'tape sothat next use.' It will be apparent thatthe element it can be easilyrendered available when an i amount of tapeis to be unrolled for use. 1

The modification shown similar to that shown in Figs. 1-3. except that;'under the outer. layer of tape and. used in-the I in vthe structure ofI am ableto attain the objects oifmy invention and provide simple yeteflicie'nt means for 1 in connection with a roll or spool of adhesivetape so that the outer endof the tape in, the roll may I be rendered"available. Great convenience will pie tape 'cuttingdevices whichjIhave?provided. Eachu'form of my deviceis relatively simple in' vsubstantially parallel to the axis of tubular memble'cable'.-: I

. comprising a. member, aboutv which the" tapeyiis.

the outer end" of tapewhich has been adhesively 1 stantially at-thecenter of said plate, said string. extending under the outer layer oftape adjacent its; outer end and across andibeyond, theiface string'maybe grasped and pulled so as to .withdraw the outer end of the tapelfromadhesivei; -cont'a'ct with the roll. w

instead of using a string for freeing theouter endi of the tape IS, atwisted, bendable wire 48 is em-' 'ployed.. The twisted wire is securedto plate ll. .5 on tube l5 by means of an eyelet member 4!,

which passes through a hole in the plate. ,i'I'he wire 48 is thusmounted for relatively free move ment relative to the plate and the rollof tape so that the end 50 01' the wire may be positioned same manner asstring 19 Figs. 1-3.

From the foregoing it will be apparent that 1 thereby result tothe"userj and further convenience will be afforded through the use ofthe sim- -structure so that it can. be cheaply andjreadily, 1. embodiedin or attached to some of the rollson.
